Your CONSOLE program must accept positive integer numbers as elements for two different SETS. Given with choices, you will perform union, intersection, and difference of the sets based on the input of the user, based on the following example:
Enter elements for Set A: (0 to end entering)
First Set: 1
First Set: 5
First Set: 8
First Set: 2
First Set: 0
A= {1, 5, 8, 2}
Enter elements for Set B: (0 to end entering)
Second Set: 6
Second Set: 2
Second Set: 0
B= {6, 2}
Choices:
A: Union of sets A and B
B: Intersection of sets A and B
C: A-B
D: Exit
Choose operation: A
Union of A and B={1, 5, 8, 2, 6}
Choose operation: B
Intersection of A and B={2}
Choose operation: C
A-B={1, 5, 8}
Choose operation: D
